Question

What will happen, if decomposers are eliminated completely from the earth?

Answer 1

If decomposers are eliminated, following thing may happen:

(i) Dead bodies of animals and plants and other dead organic matter will remain undecomposed.

(ii) After sometime the dead bodies of organisms will occupy the whole
space available on this earth.

(iii) There will be no recycling of matter between biotic and abiotic components of an ecosystem because all the matter will remain locked up in the dead bodies. Thus existence of life on the earth will become impossible.
